Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed July 23, 1914. Serial No. 852,533.

the service of distributing and collecting. articles of food, clothing,merchandise, pareels, and the like.

More specifically, the invention contemplates the fulfilling of a longfelt demand for a more suitable manner of conveying articles of food,clothing, parcels, and the like, from the exterior to the interior ofhomes, apartments, flats, room's, etc, and, at the same time, to providean improved method of delivery of outgoing parcels, such as articles forthe laundry, dye-works, and the like, for collection.

Great inconvenience has heretofore been attendant upon distributingsupplies to the home of the consumer and collecting such articles as aredesired to be returned for various purposes to the conveyor.

Such service has heretofore been rendered generally atthe danger oflosingthe articles by theft, or under the inconvenience of having theconveyor enter the private domain of the consumer.

According to my invention the risk of loss by theft is eliminated, andthe privacy of the consumers premises is preserved.

I provide, at a convenient point on the consumers premises, a cabinet orcloset accessible from both the inside, and the outside of the premises.This cabinet may consist of one or more compartments, each of which isprovided with suitable doors. This cabinet forms a seal, or look, forthe reception or deposit of articles, and is a channel through which thevarious articles of food, clothing, parcels, etc., may pass.

One object of the invention is'to provide a collection or depositingcabinet, in which articles may be deposited, and through which articlesmay be transferred only in a predetermined direction.

Another object is to provide a cabinet service door having a pluralityof compartments in which one or more of the compartments serve for thetransmission of articles in only one direction and one or more of thecompartments serve for the transmission of articles only in the otherdirection.

A further object of the invention is the provision of automatic lockingmeans Which Wlll prevent successive opening of the same door, so that anarticle may not be deposited and Withdrawn from the same side of a givencompartment.

A still further object is the provision of signaling mechanism toindicate automatically the occupied or unoccupied condition of acompartment.

The subject matter of this invention is a Special adaptation of thebroader idea disclosed in my prior copending application, Serial No.844,622, filed June 12,1914, and is, in some respects, a continuationthereof.

My prior application shows and claims an interlocking mechanism.However, the function of the mechanism in the present application isdifferent from the one above mentioned.

In the said application, the interlocking mechanism for controlling thedoors comes into action While one of the locking bolts is beingwithdrawn,-that is, the interlocking mechanism is effective only whenone of the doors is open,-the function of the interlocking mechanismbeing to prevent oppositely disposed doors from being opened at the sametime.

In the present application, the locking bolt I ofone of two oppositelydisposed doors is always engaged by the interlocking detent, andprevented from opening until released. The locking bolt of the otherdoor is completely disengaged from the interlocking detent and accesscan be gained to the interior of the cabinet through this door only.That.

operative or unlocked door, causes the interlocking detent to releasethe opposite door, and to engage the bolt of the door just operated.

I employ the term operating the door to mean an opening and closingthereof.

It can thus be seen that each door, after an operation thereof, becomeslocked and can only be operated after the opposite door has beenoperated. In the drawings forming part of this application, I haveillustrated a specific embodiment of my inven tion.

The invention is capable of wide application, and of a great variety ofuses, and while one specific embodiment is herein described and shown,this description and illustration is intended in no wise to limit thescope of the invention, but is a description of an operative embodimentfor the purpose of complying with the statutes.

In the drawings,

Figure 1 is a perspective view. of a door embodying my invention;

Fig. 2- is an elevation of the interlocking mechanism, part of thehousing being sectioned on the line 2-2 of Fig. 3 to expose the interiorarrangement of the several parts;

Fig. 3 is a View on the line 3-3 of Fig. 2;

Both Figs. 4 and 5 are views of the hall side of the cabinet;

Fig. 6 is a perspective view of the ratchet and cam mechanism whichforms part of the interlocking mechanism, as will be described later.

I have found a particular advantage in locating the cabinet in a doorstructure. This is because of the fact that the door is always keptclear of articles of furniture on the inside, and, hence, is alwaysaccessible. The door naturally marks the location of the owners premisesand is also accessible from the outside.

To illustrate the operation and utility o the cabinet service door, letit be supposed that the conveyer (milkman, grocer, butcher, laundryman,etc.,) wishes to deliver goods to the occupant of an apartmenthe willopen the outside door to one of the compartments, place the parcel orpackage within the compartment and close the door. This door is nowlocked and interlocked to prevent eX- terior removal of the parcel fromthe compartment.

A second conveyer wishing to deposit an article or parcel is apprised bythe indicator that this compartment is taken, therefore,

he employs one of the remaining compartments, going through the sameroutine as the first conveyer. The second door is thereby locked andinterlocked, and the signaling mechanism indicates that the compartmentis taken. In this manner all the available compartments in the cabinetmay be filled by conveyers without disturbing the privacy of theapartment or of the conveyer coming into the presence of the housewifeor servant within the apartment. \Vhenever the housewife or servantwishes to remove the articles deposited within the compartments, she maygain access by opening the corresponding door on the apartment side, thesignal indicating which compartments contain articles and which ones arevacant. As the articles are removed, and the doors closed, theinterlocking mechanism is automatically operated to release the bolt onthe corresponding door on the outside of a given compartment. At thesame time, the inner door is locked, and remains interlocked, until theouter door is again operated.

In order to provide a channel for outgoing packages and parcels, one ofthe compartments may be employed to allow of the operation of its doorsin such a manner as to form an outgoing channel. In this case, aremovable key or a simple combination lock may be employed on theoutside, which key or combination is placed in the hands of theauthorized conveyer.

In Fig. 1 I have shown a door 10 having the usual hanging and lockstiles, and top and bottom rails, but the space usually occupied by thepanels and cross rails of the door is, in this case, occupied by thecabinet 11.

The cabinet 11 is securely fastened to the stiles and rails of the doorand projects on each side thereof to form a symmetrical object. In theembodiment shown in Fig. 1, the cabinet comprises four compartments,

12, 13, 14 and 15, each having an outer door and an inner door forpermitting access to the individual compartment. Each of these doors isprovided with locking means 16, and adjacent each door is a sightopening 20, back of which a movable target bearing a legend isdisplayed. Similar locking means 16 are provided on the back side of thedoor and indicator openings adapted to display a signal are alsodisposed on the opposite or inner side of the door, similar to the onesshown on the outside in Fig. 1. Three of the compartments shown in Fig.1 are for use as in-going compartments or channels, and the uppercompartment 12 is to be used as an outgoing compartment or channel. Thelock 16 for the compartment 12 is shown as different from the locks 16of the other compartments, as it can be opened on the exterior to remove'7 objects from the compartment 12, while the remaining compartmentscannot be opened to re- I move an object deposited in the correspondingcompartment. "The lock for the compartment 12 may comprise a simplecombination lock, or it may be otherwise guarded, as by a key in thehands of the conveyer.

In Figs. 2 to 6 inclusive, I have shown in detail the meansfor securingthe alternate locking bolt 21 of each locking means 16 is provided witha socket shown, in Figs. 4 and 5, as a slot 22 through the body of thebolt. A. sliding rod 23 is adapted to engage the socket 22 of each ofthese locking bolts 21, in turn. When the rod 23, which forms aninterlocking detent, enters the slot 22, the corresponding bolt 21cannot be withdrawn and the door thereof cannot be opened. Thisprovides, therefore, a suitable means for preventing opening of the doorafter a package has been deposited in the corresponding compartment.Further mechanism is provided for moving the rod into the socket 22after the door is closed so that the object deposited in the compartmentmay not be removed by opening the door until some action is taken by thehousewife or maid on the opposite side of the cabinet, which wouldnecessarily occur when the object or parcel is removed. The movementthat I employ is the operation of the inner door, as it is evident thatthe object or parcel cannot be removed without opening and operating theinner door. Hence, if means be provided for alternately moving the rodinto the socket of the bolt of the door last closed, a complete cycle ofoperations will be insured, which cycle will be suitable for the purposeof insuring proper movement of the deposited article.

The rod 23 has a number of arms 24, 25 and 26. The arm 25 slides in asuitable guide 27 to prevent turning of the rod and also 'to operate thesignaling mechanism, as will be later explained. The arms 24 aiid 26 areengaged by cam mechanism adjacent each one of the locking bolts 21. Thiscam mechanism comprises a ratchet portion 30 (see Fig. 6) and a diskportion 31 bearing the cams 32. The cam and ratchet structure is mountedon bearings 33, one of which bearings passes through an opening in thecasing 34 and the other of which passes through an opening in a bracket35 mounted on the casing 34. The ratchet portion comprises a pair ofarms 36 and eccentric portions 37. A spring 38, mounted in the casing34, bears upon the eccentric portion and tends to hold the arms 36 inthe dotted-line position shown in Fig.4. When the arms 36 are in suchposition, one of these arms projects into'the path of the bolt 21 and,

. upon closing of the door and movement of the bolt to the lockingposition, which action is indicated in Fig. 5, the arm 36 will berotated to such a position that the spring presses on the opposite sideof the eccentric portion and snaps the arm structure into the full-lineposition shown in Fig. 4. This has turned the disk portion bearing thecams 32 through substantially 180 degrees and one of the .cams 32 willbe brought into engagement with the rod 26 andwill force the rod 23 intothe socket 22 of the corresponding bolt 21, as shown in Fig. 4, or asshown at the right of Figs. 2 and 3. The corresponding door cannot beopened, as it is impossible to withdraw the bolt 21 to release the same.Movement of the rod 23 to engage the socket in the bolt 21 has alsocaused actuation of the indicator or signal mechanism. The signalmechanism comprises a pair of targets 40, 41, adapted to be dis-.

played before the sight openings 20, shown more clearly in Figs. 1, 4and 5. The targets 40 and 41 are connected by a pair of arms pivoted onthe rod 42. This rod is supported by bracket 43, mounted in the casing34. The arm 44 contains a slot 45 disposed diagonally so that movementof the arm 25 in the horizontal guide 27 will cause an angular movementof the arm 44 and a consequent movement of the targets 40 and 41 in andout of position back of the sight openings. A spring-pressed catch 46holds the rod 23 at either end of its movement so as to preventaccidental displacement, as

by slamming of the door, or the like, and

consequent false operation. The locking means 16 may be provided with afixed key 47 which is set into a countersunk depression 48 to avoid asmuch as possible any projecting parts on the door itself.

The operation of the mechanism above described in detail will now be setforth briefly: When the conveyer desires to deliver a package or parcelto the occupant of the room or apartment, he selects such compartment inthe cabinet as he finds to be indicated as vacant by the target back ofthe sight opening 20 and opens the door thereof by turning the key 47.The bolt 21 slides back and allows the door to open. At this time, thespring 38 bearing on the eccentric portion 37 moves the arms 36 from thefullline position shown in Fig. 4 to the dotted line position in Fig. 4.The conveyer places the object or parcel to be delivered in thecorresponding compartment and closes the door. Movement of the bolt 21to the closed position causes engagement of the upper edge of the bolt21 with one of the arms 36 not be opened.

and. as the bolt moves inwardly. the arm 36 is actuated to turn theeccentric so that the spring 38 bears on the opposite side and forcesthe structure into the full-line position shown in Fig. 4. At the sametime, one of the cams 3:! has engaged the rod '34 and forced the sameinto the slot 22 of the locking bolt. The package or parcel is nowlocked in the compartment and cannot be removed from the outside, as theouter locking means 16 is held against operation. The movement of therod '23 to engage the slot 22 has released the lock 16 on the inside ofthe compartment which contains the package. At the same time that therod 23 was moved to the interlocking position. the signal was actuatedto indicate on both sides of the cabinet that the compartment wastaken." The housewife or maid can tell at a glance which one of thecompartments contains an article and she may then open the door removethe object, and close the door. The operation of the parts in connectionwith the closing of the inner door is the same as described for theouter door. This leaves the inner door locked against opening and leavesthe lock of the outer door in released position so that another packageor parcel may be deposited. This description applies to the compartmentsl3, l-l and 15, as they are in-going compartments. The upper compartment12 operates in the reverse order and is an out-going compartment, thatis to say. when the compartment is empty, the outer locking means 16 isengaged by the interlocking detent and can- The inner door may be openedand an article deposited therein for out-going service and closing ofthe inner door releases the lock on the outer door so that the conveyermay have access thereto, and may remove the article, parcel, or thelike. This compartment may be used for laundry. or the like, andfurnishes a very convenient means for notifying the conveyer whether hisservices are required or not, as

he can tell by the position of the indicator whether any service isdesired without making further inquiry.

It is apparentthat a great many modifications will at once suggestthemselves to those skilled in the art and that the specificmechanismthat I have illustrated is but one form of mechanism for securing theresults which I have found desirable. All of these modifications fallwithin the spirit and scope of my invention and I desire the appendedclaims to be read with as broad an interpretation as possible, as Iconsider my invention to be broadly new. It is evident that the cabinetneed not necessarily be mounted in a. door, but greater advantages aresecured by so doing, as I have indicated. It is also apparent that agreater or less number of in-goiiig and out-going compartments may beprovided and that a great number of variations of the structure may bemade to suit individual conditions.
